60% ping increase - possible things to check?

[anotherengineer]

So over the past several years cloudflare speedtest from my home to NYNY has been stable and repeatable at ~50ms ping and ~3ms jitter. The past few weeks it has been ~83ms ping and ~10ms jitter.

Don't recall changing anything. Ping tests to Chicago servers used to be 35-55ms now they are over 100ms?!

Thoughts? Using FF latest with ublock as only addon.
My son connecting things to network?

A 60% ping increase across multiple servers points to something on your side rather than the destination. A few things to check: (1) run a traceroute to your usual test servers and see where the latency jumps - if the first hop already shows high latency, the issue is local. (2) Check if something bandwidth-heavy got connected that is saturating your upload. Even small upload saturation can spike ping dramatically due to buffer bloat. (3) Check router CPU and memory from the admin panel - heavy AiProtection scanning, QoS, or too many NAT sessions can add latency. (4) Try a direct wired connection bypassing WiFi to rule out interference. (5) Check if your ISP changed your routing - sometimes ISPs re-route traffic through paths that add latency.
